The processes that are mostly studied at the LHC are caused by energetic collisions where the protons break up into their constituents, the quarks and gluons, which recombine to form composite hadrons. However, many proton-proton interactions result…
Exactly ten years ago, on the 4th of July 2012, the ATLAS and CMS experiments announced the discovery of a new particle compatible with the long-sought Higgs boson.
This discovery takes us back to the events occurring in our early…
The CMS detector, illustrated in Fig. 1, is centred around the largest and highest granularity silicon tracker ever built, including around twenty thousand detector units structured in thin cylindrical layers that extend over nearly 6 metres along…
The CMS experiment achieves the most precise determination of the strength of the strong nuclear force using the rates of production of jets at several centre-of-mass energies.
The strengths of the fundamental interactions in Nature drive the…
For the first time, the CMS experiment has employed physics-informed machine learning to observe whether the laws of physics still hold true when top quarks and Z bosons are replaced with their antiparticles and space is reflected.
We know…
The CMS experiment presents the first-ever search for a Higgs boson decaying to charm quarks when the Higgs boson is produced along with two top quarks.
The Higgs boson plays a central role in our understanding of the fundamental forces of…
By studying events with only a single energetic photon, the CMS experiment places some of the most stringent constraints to date on dark matter models and theories predicting extra dimensions of space.
One way to explore physics beyond the…
CMS presents the most precise measurement of WWZ production to date by combining Run 2 data with more recent Run 3 data.
The electroweak interaction provides a unified description of the electromagnetic and weak forces, but this symmetry is broken…
CMS explores the early stages of jet evolution in heavy-ion collisions
When heavy ions such as lead (Pb) collide in the LHC, a new state of matter called the quark-gluon plasma (QGP) is formed. The QGP is a high-temperature near-perfect liquid…
